1. Technical Field
The present invention relates to coated components, and more particularly, to paint-coated fishing components utilized in fishing reels.
2. Description of Related Art
The main types of fishing reels that are mounted on a fishing rod and used for reeling out and winding in fishing line are spinning reels, dual-bearing reels, and single-bearing reels. These types of fishing reels are provided with a reel body that attaches to a fishing rod, and a spool attached to the reel body for winding fishing line. The main parts of the reel bodys in dual-bearing reels, for example, are a frame, and side covers fastened with screws to both sides of the frame. In these side covers, protrusions, such as bosses for holding screws, are formed protruding on the reverse side of the side covers, in order to prevent the screw terminals from being exposed on the surface of the side covers. The protrusions have recesses, such as threaded sockets, whose tip ends are open, forming a so-called cap-screw configuration (in which the sockets are not bores completely penetrating the protrusions to otherwise open their base ends onto the obverse side of the side covers).
The main components of such a fishing reel (such as de covers) are made of an aluminum alloy or a magnesium alloy, for example, in order to make the fishing reel lighter. Especially when the main components are made of a magnesium alloy, their surface is coated with paint to increase their corrosion resistance. Coating with paint is carried out by spray coating or electrodeposition, for example. To coat the main components by electrodeposition, an anodic oxide film layer is usually formed on the main components, and then the main components are immersed in a paint bath to adhere the paint.
To coat the main components, such as the above-mentioned side covers, of a fishing reel by electrodeposition, the entire side cover is immersed in the paint bath, so that the paint adheres not only to the obverse side of the side cover, but also to the reverse side where the protrusion portions are formed. Herein, in particular with the protrusions of a cap screw construction, there is the risk that paint invading the protrusion openings builds up in the threaded sockets. Paint building up in the threaded sockets brings about the need to reprocess the screw hole, as it may become impossible to insert the screw all the way to the end.
An object of the present invention is, for coated fishing components formed with recesses, to make build-up of coating paint in the recesses unlikely.
According to a first aspect of the present invention, a painted fishing gear component used for a fishing reel, includes a main component and a paint film layer formed by soaking the main component with paint. The main component includes a main part, a recess portion provided with an opening formed on the main part, and a conduit formed on the main part, communicating the recess portion with its exterior.
In this painted fishing gear component, the main component is coated by immersion in paint after the main part has been provided with a recess portion and a conduit. The main part is provided with a conduit communicating the recess portion with its exterior. Consequently, excess paint is discharged through the conduit to the outside, so that paint is unlikely to build up in the recess portion.
According to a second aspect of the present invention, in a painted fishing gear component as in the first aspect, the main part is provided with a protrusion portion provided with said conduit and said recess portion with said opening at the protrusion portion's end. In this case, the main part is provided with a protrusion portion having a recess portion for attaching a screw or positioning, for example. The protrusion portion is provided with the conduit for lo communicating the recess portion with the exterior thereof, so that as in the first aspect of the present invention, paint is unlikely to build up in the recess portion.
According to a third aspect of the present invention, in a painted fishing gear component as in the first or second aspect, the paint film layer is an electrodeposition layer formed by electrodeposition. This improves the deposition of paint on the main component.
According to a fourth aspect of the present invention, a painted fishing gear component as in the third aspect further includes an anodic oxide film layer between the main component and the electrodeposition layer. This improves the corrosion resistance of the main part, as well as the deposition of the electrodeposition layer.
According to a fifth aspect of the present invention, in a painted fishing gear component as in any of the second to fourth aspect, the conduit is a slit formed in the protrusion portion. Such a slit can be arranged in the protrusion direction of the protrusion portion (that is, vertically) or perpendicular to the protrusion direction (that is, horizontally).
According to a sixth aspect of the present invention, in a painted fishing gear component as in any of the second to fifth aspect, the conduit is formed on a base side of the protrusion portion. In this case, the paint can be discharged easily, because the conduit is formed near the bottom of the recess portion.
According to a seventh aspect of the present invention, in a painted fishing gear component as in any of the second to fifth aspect, the conduit is formed extending from the opening to a base side of the protrusion portion. In that case, it is easy to form the conduit, for example by forming a vertical slot extending from the opening.
According to an eighth aspect of the present invention, in a painted fishing gear component as in any of the first to seventh aspect, the conduit is formed by cutting. In that case, it is easy to form the conduit, for example with a cutting tool, such as a T-slot cutter.
According to a ninth aspect of the present invention, in a painted fishing gear component as in any of the first to eighth aspect, the main component is made of an alloy selected from the group consisting of magnesium alloy, aluminum alloy and titanium alloy. Using a light metal, such as magnesium alloy, aluminum alloy and titanium alloy, it is possible to make a light-weight main component.
According to a tenth aspect of the present invention, in a painted fishing gear component as in any of the first to ninth aspect, the main component is a side cover attached to a frame of a fishing reel. In that case, paint is unlikely to build up in the recess portions of the protrusion portions for attaching a screw or for positioning, formed protruding from a protrusion portion side (rear side) of the side cover. Furthermore, because the conduit is formed in the protrusion portion, the protrusion portion side is not communicated with the exterior on the opposite side (obverse side) by otherwise penetrating the main part through the recess portion in the protrusion portion. Thus, water is prevented from entering from the obverse side to the reverse side through the conduit in the side cover when the side cover is attached to the frame.
According to an eleventh aspect of the present invention, in a painted fishing gear component as in the tenth aspect, the side cover is screwed to the frame, the protrusion portion is a boss portion for attaching a screw, and the recess portion is provided with a female thread into which said screw is screwed. In that case, the recess portion is a screw hole into which the screw for fastening the cover is screwed, and the conduit averts build-up of paint in the screw hole, so that reprocessing the screw hole becomes unnecessary.
According to a twelfth aspect of the present invention, a painted fishing gear component as in any of the first to eleventh aspect further includes a reinforcement member mounted on the protrusion portion. In that case, it is possible to keep up the strength of the protrusion portion, even when the protrusion portion has been provided with a vertical slot extending from the opening serving as the conduit.
According to a thirteenth aspect of the present invention, a painted fishing gear component as in any of the first to twelfth aspect further includes a cover member that is a shutoff between the conduit its exterior. The cover member is furnished to function for example as the reinforcement member of the eleventh aspect of the present invention. That is, insofar as attaching another component to the main part is concerned, the cover member fulfills an equivalent role to that of the reinforcement member that attaches another member to the protrusion portion on the main part. The cover member is made of a metal, such as an aluminum alloy or a magnesium alloy, or of a synthetic resin, and can be fastened with screws to the main component at several locations. Thus, by attaching the cover member to the main component after the main component has been painted, the conduit is blocked from the outside. Consequently, paint is unlikely to build up in the recess portion, and in particular in recess portions for accepting screws or the like, it can be prevented that water enters the gap between recess portion and screw. Furthermore, if the conduit is closed together with the opening of the recess portion, the waterproofing effect is increased even further. Also, arranging the cover member such that it is not exposed to the surface side makes it possible to improve the looks of the fishing gear component.
According to a fourteenth aspect of the present invention, in a painted fishing gear component as in any of the first to thirteenth aspect, the conduit opens to the same side as the opening. In that case, the opening of the conduit is arranged on the same side as the opening of the recess portion, so that the recess portion and the conduit can be machined easily. If additionally a cover member is provided, then these apertures can be shut easily, because it is sufficient to provide the cover member only on the side of the apertures.
According to a fifteenth aspect of the present invention, in a painted fishing gear component as in any of the first to fourteenth aspect, the conduit is formed such that the recess portion does not completely penetrate the main part. In that case, the recess portion and the conduit do not form through-holes. Therefore, if the main component is exposed to the surface side, the looks of the fishing gear component can be improved, and the waterproofing effect can be increased, because no water enters through the apertures on the other end of such through-holes.
According to a sixteenth aspect of the present invention, in a painted fishing gear component as in any of the first to fifteenth aspect, the main component is a reel body of a fishing reel. In that case, paint is unlikely to build up in the recess portions for attaching a screw or for positioning, formed in the reel body (main component).
According to a seventeenth aspect of the present invention, in a painted fishing gear component as in the sixteenth aspect, the reel body is provided with a boss portion to which another component can be screwed. In that case, paint is unlikely to build up in the boss portions which are protrusions portions to which another component, such as a lid member or a cover member, can be screwed to the reel body.
From the following detailed description in conjunction with the accompanying drawings, the foregoing and other objects, features, aspects and advantages of the present invention will become readily apparent to those skilled in the art.
First Embodiment
As shown in
The reel body 1 includes a frame 5, and a first side cover 6a and a second side cover 6b attached to the two sides of the frame 5. The frame 5 includes a first side plate 7a and a second side plate 7b to which the first side cover 6a and the second side cover 6b are attached, and a plurality of connecting portions 8 connecting the first side plate 7a with the second side plate 7b into one unit.
As shown in
As shown enlarged in
The members constituting the reel body 1 (in the following collectively referred to as main components 10) are made of a magnesium alloy. A coating is applied to the surface of the main components 10.
As shown in
Taking the main components 10 as the anode, the anodic oxide film layer 11 is electrolytically decomposed in a solution of sulfuric acid, oxalic acid or chromic acid, and a film is formed due to oxygen generated at the anode.
The electrodeposition film layer 12 is formed by electrodeposition using a cationic electrodeposition paint, whose main component is a polyamine resin. To carry out the electrodeposition, the main components 10 which have been coated with the anodic oxide film layer 11 are immersed in a bath of the electrodeposition paint, and taking the main components 10 as the cathode and electrodes arranged in the bath of the electrodeposition paint as the anode, the main components 10 are electrolytically coated with the paint by applying a dc voltage.
To paint the main components 10 by electrodeposition, it is necessary to machine the main components 10 in a cutting process first. For example, the first side cover 6a and the second side cover 6b, which are two of the main components 10, are painted after forming the recess portion 22 (hole and female thread) and the conduit 25 in the protrusion portion 20.
In the first side cover 6a and the second side cover 6b of this dual-bearing reel, the protrusion portions 20 are provided with the conduits 25 communicated with the recess portions 22, so that when they are painted by electrodeposition, excess paint is discharged through the conduits 25 to the outside, preventing a build-up of paint in the recess portions 22.
Second Embodiment
As shown in
The reel body 102 includes a reel body 102a provided with a space inside, a lid member 102b and a cover member 102c mounted detachably to the reel body 102a to shut the space in the reel body 102a, and a bearing member 102d (see
The reel body 102a is made, for example, of a magnesium alloy, and is formed unitarily with a T-shaped rod attachment leg 102e extending horizontally at the top of the reel body 102a. As shown in
The lid member 102b is made, for example, of a magnesium alloy, and screwed at three locations to the left side of the reel body 102a at a second screw portion 122, a third screw portion 123, and a fourth screw portion 124, as shown in
The cover member 102c, which is for example made of a magnesium alloy, covers the rear end portion of the reel body 102a and is fastened at a first screw portion 121 to the reel body 102a at the upper rear.
As shown in
The oscillation mechanism 106 shifts the spool 104 back and forth, shifting back and forth the spool shaft 115 to which the center of the spool 104 is coupled via a drag mechanism 160.
As shown in
The rotor unit 116 includes a cylindrical portion 130, a first rotor arm 131 and a second rotor arm 132. The cylindrical portion 130 is attached to the reel body 102a and can rotate freely around the spool shaft 115. The first rotor arm 131 and the second rotor arm 132 are arranged in opposition to one another on the sides of the cylindrical portion 130. The cylindrical portion 130, the first rotor arm 131 and the second rotor arm 132 can be made, for example, of an magnesium alloy, and are formed in one piece.
As shown in
As shown in
The following is a detailed explanation of the configuration of the first to third screw portions 121 to 123 of the reel body 102a.
As shown enlarged in
The cover member 102c is a shutoff between the first conduit 121c its exterior. The first conduit 121c is provided with an aperture on the same side as the first opening 121a. Furthermore, the first conduit 121c is formed such that the first recess portion 121b does not bore through the reel body 102a.
As shown enlarged in
As shown enlarged in
All components of the reel body 102a are made of a magnesium alloy, and as in the first embodiment, they are painted by electrodeposition after the screw holes have been formed. The details of the electrodeposition are the same as in the first embodiment, so that their further explanation has been omitted.
In a spinning reel with this configuration, the reel body 102a is provided with first to third conduits 121c to 123c communicating with the first to third recess portions 121b to 123b, so that when it is painted by electrodeposition, excess paint is discharged from the first to third conduits 121d to 123d to the outside, preventing a build-up of paint in the first to third recess portions 121c to 123c.
Other Embodiments
(a) The first and second embodiments have been explained taking a dual-bearing reel and a spinning reel as examples of paint-coated fishing components, but they are not thereby limited, and the present invention can be applied also to single-bearing reels or any other kind of fishing reel.
(b) In the first and second embodiments, the main components 10 are made of a magnesium alloy, but they can also be made of an aluminum alloy a titanium alloy or any other suitable metal.
(c) In the first embodiment, the conduit 25 is formed as a horizontal slit in the protrusion portion 20, but it is not thereby limited, and the conduit may also be formed as a vertical slit. Moreover, as shown in
(d) In the third screw portion 123 of the second embodiment, the third conduit 123c was formed such that it communicates the third recess portion 123b with the opening on the side of the bearing member 102d, to which the rotation transmission mechanism 114 is mounted. However, it is also possible to form the third conduit 123c by letting the screw hole 123d for mounting the guide shaft 106a of the oscillation mechanism 106 penetrate all the way to the third recess portion 123b, as shown in FIG. 13.
According to the present invention, in a painted fishing gear component having a main part provided with a recess portion, the main part is provided with a conduit communicating the recess portion with its exterior, so that excess paint is discharged from the conduit to the outside, preventing a build-up of paint in the recess portion.
While only selected embodiments have been chosen to illustrate the present invention, to those skilled in the art it will be apparent from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims. Furthermore, the foregoing description of the embodiments according to the present invention is provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
